SERVICE INFORMATION

When diagnosing an infotainment issue or after replacement of the AV Control Unit, it is necessary to verify the current software version of the AV Control Unit to determine if a software version update is required.

Use the vehicle tables in this bulletin to determine the current software version, if the AV Control Unit requires a software version update, and which procedure to use to update the AV Control Unit.

The software updates in this bulletin are to address stability improvements and "bug" fixes.

IMPORTANT: If the client is experiencing a software related concern, refer to ITB21-011 to verify if the client concern is a hardware or software related issue. If the concern is a software related issue, review the information in this bulletin to update the AV Control Unit as needed.

Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this applies to your vehicle.

REQUIRED SPECIAL TOOL

• One of special tool USB drive J-52727-1 (new tool number NI-52727-1) has been previously shipped to each retailer (Figure 1).
• Do not use any other USB drive to perform the procedure in this bulletin.
• Additional USB drives may be purchased from Tech Mate: www.techmatetools.com or 1-833-397-3493.

HINT: The update-software only needs to be downloaded once and can then be used continuously on multiple APPLIED VEHICLES.

HINT: The update-software must be the only file on the USB drive.
